PRESERVING-JAR.

Specification of Letters Patent.

Patented June 1,1920.

i Application led October 20, 1919. Serial Nr. 331,968.

To all whom it may concern.'

Be it known that I, WALTERV F BALcoM, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Preserving- Jars, ofwhich the following is a specification.

My invention relates to new and useful improvements in preserving jars.The object of the invention is to provide efficient and simple means forsealing the lid of the jar after receiving the contents and a furtherobject is to provide a construction whereby the cap may be removed afterthe jar has been sealed, Without obstruction from the sealingl material,as will hereinafter more fully appear from the description toI follow inconnection with the accompanying drawings. l

Referring to the said drawings in general terms,

Figure llis a top plan view of the jar with the lid thereon, and Fig. 2is a vertical section through the center thereof.

The jar -3- is preferably made of glass such being the mostsuitablevmaterial for jars of this type. The mouth or neck -4- thereofis contracted in diameter and is provided with exterior screw threads-5-. The relative diameters of the two parts of the jar, to wit, thebody and the neck is such as to provide a substantial annular offset -6-between the two parts, which in turn provides an annular channel -7-between the neck and body. The said channel -7- is inclosed by taperedwalls 4-8- on the inner and outer sides thereof. The inner wallterminates in an inner annular shoulder Q-,- at the base of the neck andthe outer tapercd wall terminates in the annular lip -G- which extendsup above the shoulder -9-. The lid 0r cover -1- has grooves in the innerside thereof which receive the threads -5- and the circularedge isformed in a projecting annular taper -11- with an interior shoulder--12. The channel 7 formed as described, be-

tween the neck and the body of the jar, re-

ceives a quantity of sealing material -2- which is retained therein whenin soft condition, by the upwardly extended lip -64- of the jar. lVhenthe cover -1- is screwed on the neck of the jar, to close it, the edge-11- of the cover enters the sealing wax -2- and the two shoulders 9 and-12- close upon a portion of the wax lying therebetween and the coverand the jar thus become thoroughly sealed. Vhen the jar is being handledprior to placing the lid thereon, the lip -G prevents any of the waxfrom running out of the channel, and

the construction is such that a suitable quantity of sealing wax may beplaced in the channel.

Owing to the tapered character of the edge l1- of the lid, and thestraight shoulder *9- and corresponding straight surface of the lidabove the shoulder 9-, the lid is easily removed by unscrewing withoutany resistance from the sealing material in the channel -7-.

Having described my invention, I claim:

A preserving jar having the neck portion thereof of such diameterrelatively to the body of the jar as to provide an annular channelbetween' the base of the neck and the outer circumference of the body ofthe jar adapted to contain sealing material, the,

inner annular wall of said channel joining the neck of the jar at thebase thereof in a horizont-al annular shoulder, and the outer annularwall of said channel terminating in an annular tapered lip which extendsabove said horizontal annular shoulder, and a screw cap having anannular tapered edge, and a horizontal annular shoulder joining theinside of said edge at the base thereof, said edge being adapted toenter the sealing material in said channel, and said horizontal annularshoulder being adapted to engage the sealing material above the innerannular shoulder of the neck, when the said cap is screwed in positionon the neckof the jar.

In testimony whereof I alx my signature.

IVALTER F. BALCOM.
